The Lowdown
Alright, grab a coffee, let's settle in and have a proper look at what's on the table for Karramarro over the next couple of weeks. It’s a bit of a patience game I’m afraid, but there is a light at the end of the tunnel.
Right out of the gate, we’ve got a long, quiet spell. This is a point break, an advanced wave that doesn’t like to show up often, and we’re in one of those stretches where it’s holding back. From now and right through until around the 22nd of August, it’s flat or pretty much useless. We’re talking small dribbles of swell, mostly around 1 ft to 2 ft, with periods under 10 seconds and combined energy levels that barely hit triple digits (mostly between 22 and 160). The water temp is sitting at 75°, which is much warmer than normal for this time of year, but that’s about the only excitement. The wind is often cross or cross-onshore, and the forecasts all scream “poor surf conditions.” Honestly, you’d be wasting your time paddling out.
Now, the 17th and 18th of August see a tiny lift in size, with waves just sneaking over 4 ft, and we get some glassy mornings on offer. But the period is a short, weak 6-7 seconds, and the energy is marginal. The surf quality is still considered poor, so it’s not going to be worth the drive.
The first real glimmer of hope comes on the morning of Saturday the 22nd of August. We get a glassy morning, a long-period groundswell from the NW at 12 seconds pushing 2 ft of swell, but the combined energy jumps to 193. It’s described as “surfable waves but very ordinary conditions” – a tease, really. It’s still not the one.
But then… hold onto your board. The standout is the morning of Tuesday the 25th of August. This is the one to circle on the calendar. We’re looking at 5 ft of clean swell from the WNW with a solid 10-second period. That combined energy reading hits 846, that’s proper wave energy, and it’s forecast to deliver “very good surf conditions.” The wind is glassy out of the NNE. This is a proper groundswell, so it’s going to throw down some clean, lined-up waves at this point break. Given the crowds can be *often* a thing here, expect some company, but on a day like that, who cares? The afternoon stays clean but the energy drops a bit, so make the most of the morning session.
So, to keep it simple: sit tight through a lot of flatness. The morning of the 25th is your golden ticket. Anything before that is a gamble you’ll probably lose.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
